Contents of cadmium, iron and manganese in various parts of manganese nodules and ferromanganese crusts

Mn nodules and ferromanganese crusts from the Pacific ocean were retrieved during expeditions of the R/V Vytiaz and analysed for their chemical composition. Cadmium contents were determined by atomic absorption spectrometry with non-flame atomization and calibrated by means of rock standards from the U.S. Geological Survey BCR-1, G-2, GSP-1 and AGV-1. The Fe and Mn in these samples were also determined by classical wet chemical analysis.
